Application filed May 19,

To 'aN whom t may concern Be itknown that L LUCIUS d. PHELPS, a

'citizen ofthe United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented new and usefulimprovements in Homogenizers, of which the following is a specification.

This invention is an attachment employed in connection with internalcombustion engines, and providing means disposed within the intakemanifold of the engine for impingement by the combustible mixturepassing through the intake manifold so as to break up said mixture andthereby cause complete vaporization of the fuel.

More specifically the invention provides impingement elements, one ofwhich functions within the intake manifold just beyond the carburetor soas to cause initial breaking up of tlie-'vaporized mixture. A secondimpingement element is provided in the transversely extending portion ofthe intake manifold which leads to the respective cylinders, saidelement extending across the perpendicularly disposed portion of themanifold so as to be impinged by all of the combustiyble mixture fiowingthrough the manifold.

The breaking up of the combustible mixture will be completed by thesecond impingement element, and as a consequence thorough vaporizationof the fuel will occur.

The invention will be vreadily understood from the following descriptionof the accompanying drawings, in which: p

Figure 1 is a side elevation of an internal combustion engine showingtheintake manifold partially broken away and having the attachmentpositioned within said intake manifold.

Figs. 2 and 3 are detail transverse sections on the lines 2-2 and 3-3 ofFig. 1.

The attachment is employed in connection with a usual engineconstruction including carburetor 1 having flanged coupling member 2 towhich the intake pipe 3 is connected by a co-operating flange coupling4. The intake manifold includes a usual horizontally disposed portion 3acommunicating with a vertical portion 3b which in turn communicates witha vtransverse extension 3 leading to the respective cylinders of enine5.

The attachment forming the present invention includes two impingementelements preferably formed of metallic screening of Specification ofLetters Patent.

suitable mesh. One of these elements comirises a conical structure asshown at 6 and preferably formed of .a single sheet of screening wrappedupon itself so as tolform a cone having an open base and a closed apex.A metallic stiifening ring 9 is preferably received within the open baseof 'the conical screen. The cone is mounted in the portion 3a of theintake manifold with the base of said cone received against the usualbeveled lip 10 at the coupling flange at of the manifold, and by thisarrangement it will be seen that when coupling iianges 2 and l aresecured together, the impingement elements will be supported in theintake manifold.

The apex of the cone extends in the direction of flow of the combustiblemixture through the intake manifold and may be curved to conform to thecurvature of the.

intake manifold as it is extended to form 'the portion 3b thereof. Bythis arrangement it will be seen that all of the combustible 'mixturewiil enter the cone and must pass through the screening forming thesaine o'uring its flow through the intake manifold, and as a consequencethe mixture will' be broken up so as to increase the vaporizationthereof.

second impingement element is provided in the transverse portion 3 ofthe manifold, and preferably includes a screen which is .transverselybent and rebeiit so as to form the angularly spaced'portions 12 of saidscreen, which form a structure adapted to be readily received in thetransverse portion of the manifold over the opening from the same to thevertically disposed portion 3b of the manifold. By Athis arrangement itwill be seen that the combustible mixture entering the transverseportion of the manifold will abut against portions 12` of theimpingement element during the passage there of to the engine cylinders,and as a consequence thel vaporization of the fuel will be increased soas to form a more efficient combustible mixture. y

`Various changes may be made without dev parting from the spirit of theinvention as claimed. f `What is claimed is: i

'1. The combination with an internal combustion engine including anintake manifold limi l having a transverse l a perpendicular extension,-ofan impingement element in said manifold for breaking up thecombustible mixture and including larly disposed superimposed layers,said screen being received in said transverse por-- tion of the manifoldso as to extend across the perpendicular extension of said manifold.

3. An impingement element of the charl acter described comprisingascreen transversely bent and rebent to form angularly disposedsuperimposed layers. V

Ail. An impingement element of the char'- acter described comprisingforaminous material recurrently bent transversely to provide superposedlayers which gradually decrease in Width from the innermost layer.

In testimony whereof I `have signed my name to this specification.

` Lucius J. PHELPs.
